Huge SimCity Update Coming Next Week
According to the SimCity official Forum, the game is going to be receiving a major update next week and will require the servers to be shut off for a few hours. According to the post:
"Because this is our first significant Update, we wanted to inform you in advance that we’ll be taking down all servers for a few hours while these changes are being issued," Maxis went on to say that "Choosing a time to issue a major Update is never easy, but after looking our peak player time, we've concluded 1pm PST is the best window for us to make these improvements." They also say that the update will be "well worth the wait."
The update adds several bug and glitch patches as well as a plethora of tweaks and new things to the game. I wont list them here (as the list is pretty big) but you can find the full in detail list on the official SimCity Forum.
